 ORDENONE DEODORANT EFFICACY STUDY
 
OBJECTIVE: The purpose of the study was to evaluate the effectiveness of Ordenone Deodorizer in a personal stick deodorant product to reduce or eliminate underarm odors.

PROTOCOL SUMMARY:
  • The study involved 12 volunteer subjects. Six males and six females of varying ages.
  • Subjects were instructed to abstain from using any type of deodorant not provided for the study or to use perfumed products other than fragrance-free soap, both before and during the test period. Additionally, no clothing laundered with detergents or fabric softeners that contained fragrance was permitted. Participants were instructed to abstain from smoking, eating spicy foods, consuming alcoholic beverages or swimming for a period before and during the study period.
  • Subjects were given specific personal washing instructions and product application procedures to limit variations. Deodorant products were provided to participants both with and without Ordenone Deodorizer #80365, one for each underarm to provide comparison data.
 

On a scale of 1-6, each subject was evaluated twice daily by four qualified evaluators to determine perceived malodor levels. The subjects were evaluated over a three-day period. The results and summary of the evaluations shown on the attached graphs.

Subjects were also observed for irritation before the commencement of the study and at each odor evaluation. The results of the secondary perceived irritation study are provided on the attached table. 

CONCLUSION: PERSONAL DEODORANTS INCORPORATING ORDENONE DEODORIZER CLEARLY ARE EFFECTIVE IN THE REDUCTION OF UNDERARM ODORS, WITHOUT PERCEIVED IRRITATION.

Note: Available long-term sensitization/irritation study results show Ordenone safe to use in personal care products.

 
 


 

Scores for each evaluator range from 0 to 6 and are shown as an average for all participants. The scores for each participant varied but were rated consistently amongst all evaluators. The results for evaluators are shown as an average for all twelve participants. Score of -0- indicates no perceived odor. Score of 7 indicates high body odor. No perceived irritation was noted by use of Ordenone.

 

 

 

 

QUALITATIVE SENSORY EVALUATION OF ORDENONE® ON A SELECTED MALODOR

 

OBJECTIVE:  The purpose of the study is to evaluate the effectiveness of Ordenone as a noisome odor control agent when applied to a feminine hygiene pad.

MATERIALS REQUIRED:

  • Clarissa® Super Maxi Pads Mfg. by Hospital Specialty Co.
  • Suitable glass jars with lids to contain the test materials.
  • A malodor solution of 2% amine in water.  (Supplied by Belle-Aire.)
  • An appropriate number of eyedroppers to apply malodor to the test and control samples.
TEST PREPARATION:

Square samples of the feminine pads are cut from the middle or most likely area of the pad to receive wearer's efflux discharge.  (Generic Clarissa® Super Maxi Pads manufactured by Hospital Specialty Co. have been selected for this evaluation as there is no odor control or fragrance in this generic pad.)  The size of the squares should be appropriate to the glass jars selected for the test, but are nominally 2.5 cm square.  A square is placed in each jar and covered with its lid. A 10% solution of Ordenone in water is prepared to treat one jar of generic pad material. The other jar, containing untreated generic pad material is used to comparatively validate the reduction of malodor in the generic pad that is treated with Ordenone.

PROCECURE:

 

 The 10% solution of Ordenone is sprayed on one of the generic pads to achieve 0.042 grams of Ordenone on the pad.  This jar is labeled with Ordenone.  1-3 drops of the amine solution are placed in the middle of each pad of both jars that are then immediately covered with the jar lid. 

After one minute each jar is opened and evaluated for the presence of amine odor.  Immediately after evaluation the jar is resealed for the next evaluation period.  Restating, the generic pad control jar is used to qualitatively evaluate the comparative reduction of odor in the pad containing Ordenone.  The process should be repeated over a minimum of 2-hour intervals to evaluate the continued control of odor over the maximum time of use of this type product before it is discarded.  The maximum time for the study was 8 hours, or 4 evaluation periods.

CONCLUSON:

The pads treated with Ordenone demonstrate a remarkable reduction of the amine malodor almost immediately upon contact.  No detectible amine odor was perceived on the Ordenone treated pads throughout the 8-hour evaluation.  The control pads retained a strong amine odor.
